MessagePartCollection Class

Represents a collection of instances of the MessagePart class. This class cannot be inherited.

Namespace: System.Web.Services.Description
Assembly: System.Web.Services (in system.web.services.dll)

public sealed class MessagePartCollection : ServiceDescriptionBaseCollection
public final class MessagePartCollection extends ServiceDescriptionBaseCollection
public final class MessagePartCollection extends ServiceDescriptionBaseCollection
Not applicable.

The MessagePart class corresponds to a Web Services Description Language (WSDL) <part> element enclosed by the <message> element, which is in turn enclosed by the <definitions> root element. For more information about WSDL, see the specification at http://www.w3.org/TR/wsdl/.

The following example demonstrates the use of the methods and properties exposed by the MessagePartCollection class.
